Overview

dCache is a sophisticated system that allows transparent access to files on disk or stored on magnetic tape drives in hierarchical storage managers (HSMs). dCache is a joint venture between the Deutsches Elektronen-Synchrotron (DESY), Fermi National Accelerator Laboratory (FNAL), and Nordic e-Infrastructure collaboration (NeIC).

Obtaining a computer account on SDCC systems requires a valid guest appointment or employment at BNL and successful completion of BNL Cyber Security Training (GE-CYBERSEC). Once these prerequisites are complete, new users can “Get Started” by visiting the SDCC home page at https://www.sdcc.bnl

How to change SDCC facility passwords

SDCC facility users can change their Kerberos and/or email passwords using the following procedures:

Domain-Based Message Authentication, Reporting & Conformance (DMARC) Policy

BNL Cyber Security has implemented an email authentication policy called DMARC, a domain-based message authentication, reporting, and conformance policy that relies on the DKIM (DomainKeys Identified Mail) and SPF (sender policy framework) email authentication protocols.

 Authentication failure issues

• There is a 120 seconds limit to enter the OTP token, if the time limit is exceeded gives the message of authentication failed and to try again.
• When the wrong credentials are given(either kerberos password or OTP token) couple of times, the SDCC account will get locked out and in this case NX will give "Authentication Failed, please try again" message.

MFA Deletion process

Don't forget to delete the existing token on your mobile device or browser before creating a new one.
